Application med may 12, 191s. serial Nt. 96,978.

Rockford, in the county of W lnnebago and State of Illinois, haveinvented certain new and useful Improvements in lVinders, of which thefollowing is a specification.

One of the objects of this invention is tol produceimproved means forpressing the receiving yarn-mass against the driving drum.

Another object of the invention is to provide improved means forthrowing the receiving yarn-mass out of operation upon the exhaustion ofthe yarn.

Another object is to provide means for automatically placing thedetector mechanism in position to receive anew thread.

Another object is to provide improved means for restoring the receivingyarn-mass to operative position.

A further object is to provide means fr preventing the receivingyarn-mass `from being returned to operative position if the yarn masshas reached the desired diameter.

Fig. 6 isa ragmental front elevation of the Winder. Fig. 7' is a View on theorder of Fig. 1, but showing a different position of the parts. Fig. 8is a view showing the operation of the means for preventing the returnof the receiving yarnmass to operative position. Fig. 9 is a fragmentalhorizontal sectional view of the detector mechanism.

A Winder embodying my invention may comprise any desired number ofwinding units each adapted to rewind yarn from successive bobbins a.onto a tubular carrier b to form a cylindrical cross-wound yarn mass `rcheese c. The bobbin a may be supported in any suitable manner; forexample, it may be non-rotatably supported for the drawing of the yarnoff the tip of thebobbin, or it maybe rotatably supported for theunwinding of the yarn from the side of the bobbin.

Herein is shown a bobbin-holder A which issubstantially similar to thebobbin-holder shown in Patent No. 1,045,879 dated December 3, 1912.

The cheese is rotated through peripheral contact with a drum 1 fixedupon a continuously-rotating shaft 2. The drum l is provided with` aperipheral cam-groove 3. When the cheese is in peripheral Contact withthe drum 1, the cheese is rotated and the yarn is rapidly traversed orguided back and forth. l

In front of the cam drum,1 is a standard 4 .having a bearing 5 at itsupper end. (See Fig. 7). A cheese-supporting lever 6 is provided uponone side and near one end with a pivot 7, which is mounted inthe-bearing 5, said pivot being rigid with lthe lever. At the end of thelong arm of the lever 6 is means for rotatably supporting the cheese,which means may be ofany suitable character, as for example, that fullydisclosed in application Serial No. 74,290 filed January Means isprovided for pressing the yarn mass against the drum 1. Herein is showna lever 8 pivoted at 9 to the standard 4. IThe upper end of the lever isrounded, as at 10, and has a notch 11 therein to receive a. lug 12 fixedto the pivot 7 of the lever 6. When the cheese is in contact with thedriving drum 1 the lugI 12 lies in the notch 11, and a. spring 13 actingupon the lever 8 presses the cheese against the drum. At the lower endof the lever 8` is a handle 8.

The means for automatically vremoving the cheese from the cam drum' 1when the yarn exhausts comprises a link 14 pivoted at its upper endtothe short arm15 of the lever 6, which link may be in the form of anelongated loop. A projection 16 on the standard 4 extends through theloop and cheese is withdrawn from the cam drum. The hook 18 is xed upona shaft 19 which may be rocked by any suitable means.

The means for swinging the link 14 within reach of the hook 18 comprisesa vertical rock shaft 20 having fixed thereto two detector fingers 2larranged to be yieldingly pressedl against the running thread by meansof a v torsion spring 22 surrounding the shaft 20. 23 are stationaryfingers constituting a grid against which the running thread is pressedby the detector fingers 21. 24 is -an arm fixed to the detector shaft20. When the thread exhausts, theshaft 20 is turned by the spring 22,whereby the arm 24 swings against the link-14and carries said linkwithin the range of action of the hook 18. Upon the next .downwardmovement of the hook the link 14 is pulled downward so as to raise lthecheese off the driving drum l and remove the lug 12 from the notch 11.As the lug 12 is being forced out of the notch" 11, the lower portionofthe lever 8 is caused to swing forward a little, but as soon as the lughas left the notch, the spring 13 swings the lever 6 against a stop 25(Fig..7), the action of the spring being yieldingly checked by a dashpot26. The surface 10 is thus placed under the lug 12, whereby the cheeseis prevented fromdropping back into contact with the drum.

The means for returning the detector fingers 21 into position tolreceive a new thread comprises an arm 27 fixed to the shaft v20 inposition to be engaged by the lever 8 when said lever is drawnrearwardly A by the spring 13. In such movement of the lever 8, theparts carried by the shaft 2O are swung into the thread-'receivingposition 4shown by the dotted lines in Fig. 9.',When

the ar'm 24 is thus moved into the dottedline position indicated in Fig.9, the link 14 swings forwardly away from ythe hook 18.

28 (Fig 3) indicates a sheet-metal structure secured to the vmachineframe and having appassageway 22a through which the running threadvextends.

yThis passageway serves to guide the thread of a new bobbin into runningposition. 29 is a Haring en'-,

trance to said passageway. '30 is ahook 1 located at one side of theentrance. The

ist

hook 30.keeps the thread of a new bobbin in position to be engaged bythe detector fingers 21 as said lingers swing into operative position.Between the detector fingers and the passageway '28 the thread extendsthrough a stationary guide or hook 31 (Figs. 1 and 9).

The means for 4IJreventing the cheese from being returned into contactwith the drum 1 if the cheese has reachedthe desired diameter comprisesa gage 32 which is pivoted to the machine frame at 33 in position to betouched and moved byv a full cheese in the throwing-out movement of the4latter. The

gage 32 yis adjustably connected by means of a clamp screw 34 with anarm 35. The lower end of the arm 35 is yieldingly connected to the rearend of a link 36 by any suitable means, as', for example, a spring 37connecting said link to a pin 38 set in the arm 35, said pin extendingthrough an elongated opening 39 in the link. The forward end of the linkis pivoted to a Stop 40 which is pivoted to the machine frame at 41,said stop being arranged to lie behind the upper end of the lever 8 toprevent movement of said lever, In the form herein shown, the gage 32 isconstructed to serve as a counterweight which normally holds the stop 40in the position shown in Fig. 7, in which position jit does not,vinterfere with movement of the lever 8.

Before replacing a full cheese with a as shown in Fig. 8.,

cheese core b, the operator takes hold of the lever 6 and swings itforwardvinto the .position shown at m in Fig. l. The lever 6 issupported in such position through contact of a lug 42 with'the surface43 of the lever 8, said lug being fixed to the pivot 7. When the lever 6is thus swung forward, the upper end of the link 14 swings downwardlyand bobbin holder; places the bobbin thread within the hook 30. (Fig.3); finds the4 thread end upon the cheese core; 'unites the bobbinthread and the cheese thread in any suitable way; swings the lever 6into the position shown in Fig. 7, the cheese being held 0H the drum lby the lug`12 which rests upon the surface 10; and rotates the I cheeseby hand in the direction to wind up the thread. thus taking the slackout of the thread and preventing any kinks that may have been formedfrom being wound upon the cheese. The operator next draws-,the lever 8forward to allow the detector fingers 21 to move into contact with thethread and 'to remove the surface 10 from beneath the lug 12 and bringthe upper end of the wall 11a of thenotch 1l into contact with the lug12. The operator then allows the spring 13 to draw'the lever 8 slowlyrearward. As the lug 12 passes down into the notch 11, the cheesedescends upon the cam drum, the operator-keeping the thread .taut

as it approaches the running position.. After space between every twoadjacent` guards provides a passage 46 (Fig. 6) through which the newthread passes when moving rearwardly into contact with the cam drum Asthe new thread passes into running posiv tion, .it springs into the hook31.

Vhen the thread of an incomplete cheese exhausts, the cheese isautomatically moved into the position shown in Fig. 7, and the operatorrepairs the break or ties on a new bobbin While the cheese occupies suchposition.

The Winder is also adapted to unwind defective yarn masses carried bycores b.

Such yarn masses may be supported for the rewinding operation in anysuitable manner. Herein is shown a stand. 47 (Fig. 5), arranged to beplaced upon the floor beneath the bobbin holder A. Upon said stand is astud 48 to fit into the tubular core b of a cheese placed in horizontalposition upon the support 47. The thread from the cheese passes upwardlythrough the space between guide wires 49 as indicated by thedot-and-dash line 50 in Figs. 1 and 6.- The thread 50 also passesthrough a suitable tension device 51, under a guide 52 and to thedetector fingers 21.
